Union County Falcon Cam

Conserve Wildlife Foundation is partnering with Union County on the new Falcon Cam located on the roof of the County Courthouse in downtown Elizabeth, New Jersey.


“This Falcon Cam will provide an enriching experience for County residents of all ages, and for online visitors from all over the world."


Union County Nestbox News:

April 25

As you can see, things are getting a bit interesting in Elizabeth. The new female, who is just barely old enough to breed, has laid her first two eggs. Now she is incubating both her rivals eggs and her own. The first two eggs were laid on March 22 and March 24 and incubation began around March 28. Typically falcons incubate for 32 days, but with some of the gaps in steady incubation that could push hatching till early next week, but either way, we will be watching for hatching starting on April 29, if the eggs survived... If they don't hatch before May 5-6 then the chances of them hatching diminish.

The new eggs just complicate things even more. If just one of her rivals eggs hatches, it puts her own eggs in serious jeopardy of survival. Her efforts to incubate would slow as the young get older as her instincts would force her to care for your rivals young over her own. All of this depends on whether or not the eggs hatch. For that, only time will tell!

Not much has changed since our last entry. The male seems committed to make sure that his brood survives, despite loosing his previous mate. The pair has been seen performing courthship displays, including bowing "e-chup" calls. The new female, 91/BA has even come into the nest and toyed with the idea of incubating the eggs but has yet to claim them as hers.

April 6

What we've witnessed over the past 48 hours has been the true, unfiltered behavior of nesting peregrine falcons and evolution at work. Natural selection is the process of evolution where only the fittest survive to produce offspring. As it turns out, 91/BA "Cadence" is more fit than the resident female. We are in communication with employees of Union County, who are watching for the possibility of finding the injured resident female. If she is found and brought to a local rehabilitator then we will hear about it.

It will be interesting to watch and see how this season unfolds. With the resident female being defeated by 91/BA, the male is still trying to ensure the survival of his (and her) offspring. However, he will need to eat, so he will need to leave the eggs to forage. If the eggs are not kept warm, then the embryos will fail to develop. We're doubtful that 91/BA would incubate another birds eggs, but nothing is certain at this point. Either way, he will need to develop his relationship with her (the new female) and the chances of these eggs hatching is slim. Only time will tell what the ultimate outcome would be.

April 5

The fate of the resident female remains uncertain. The pair has fought since late February to defend their territory against Cadence, the relentless female from Rochester, NY, who today appears in and around the nest while the male continues to incubate the eggs. At two years old, Cadence is young to lay eggs of her own although it is possible. Only time will tell if she will adopt the nest with the male, and how the two will interact as incubation of the two eggs has already begun.

April 4 (Contd.)

The 2 year old intruding female 91/BA, named Cadence from Rochester, NY was spotted again at the nest on top of the Union County Courthouse. A tangle above the nest between the two female's did not help the resident female who already had an injured (left) wing. These territorial battles can be extensive and leave all involved exhausted. Kathy Clark, ENSP Zoologist was watching and at one point she saw 91/BA hit the resident female at around 5:30pm. After that, the resident female was not seen again.

Incubation has begun and the battles seem to have ended, with the resident (unbanded) female successfully defending her eyrie (nest), despite gaining some new battle scars. Viewers have watched the male perform the majority of incubation duties, which is usually done by the female. She's obviously been under a great deal of stress from defending her eyrie and should settle down more on the eggs as they get back to their normal routine. Peregrines begin incubating after they lay a full clutch. With there being only two eggs (most lay between 3-4 eggs) this is likely due to stress from the battles this spring. The second egg should have been laid on March 26 since peregrines typically lay an egg every other day (second egg was laid in the evening of March 24). We believe that she could have "dropped" an egg, which means that she could have laid the egg during a mid-air battle with the intruding female. A reduced clutch is not a bad thing and the peregrine falcon population has been quite stable over the past several years. Nests on towers and buildings continue to be the "backbone" for the continued stability for the statewide population, while nests on natural cliff sites continue to be much less stable due to their inherent nature of being suseptible to predators and weather.

Hatching should begin during the last week of April.

March 29

Female intruder returns to nest and a battle ensues with footage of the female peregrine falcons locking talons and falling from the sky. Both resident male and female peregrine falcons are viewed on the livestream later that afternoon. Intruder has been successfully chased off for the time being.

March 25-28

Periodic sightings of intruder. Resident male and female take turns defending nest and incubating eggs.

March 24

The resident peregrine falcons defends nest against intruding female and sustains injuries to her chest and left wing. She lays 2nd egg following this altercation.

Union County Falcon Cam

A pair first attempted to build a nest on the roof of the County Courthouse in 2005, but windy conditions were an obstacle. In 2006 County workers installed a repurposed dog house to provide a wind shield, acting on the guidance of wildlife experts with the New Jersey Department of Environmental Protection. Every year until 2015, the same nesting pair has raised chicks in the doghouse since then.

In 2015, this nesting pair had four eggs, beating the statewide average of 2.25 young per active nest. They also hatched all four to achieve a 100 percent success rate, well above the average rate of 71 percent.

However, earlier this year in 2016 a new female took up residence in the nest. Leg bands indicate that she was born in a nest located at Throgs Neck Bridge in New York City in 2010.

Conserve Wildlife Foundation partners with Union County and the NJ DEP on a Peregrine Falcon banding program. Thanks to the partnership, offspring from the County Courthouse pair have been observed around the tri-state region, where they have raised chicks of their own.

The new Falcon Cam live stream includes two cameras. One provides a view of the nest interior and an infrared video image for night time viewing.

A second camera enables observers to track the falcons’ behavior while perched outside of the nest. An audio feed will also be available later this year. With the Falcon Cam, Union County becomes one of only two places in New Jersey with a live peregrine falcon web link. The other web cam is located at a nest in Jersey City and is managed by the biologists of Conserve Wildlife Foundation.

Jersey City Falcon Cam

CWF's new partnership stems from the long legacy of our Jersey City Falcon Cam. After 16 seasons of dedicated research, there has been much uncertainty within the past two years. With multiple males coming in to use the eyrie - it has not been a productive time.

However, we are not giving up! CWF hopes that our new partnership in Union County will in turn continue to support our efforts in Jersey City.

CWF’s Soaring with STEM program educates children about New Jersey’s unique natural resources and the rare wildlife that shares our environment using the Union County Courthouse live falcon web cams as the primary technological learning tool. Through interactive and engaging classroom and assembly presentations, our experienced educators bring wildlife into your school. Students are fascinated to discover that these raptors nest and raise young each year right in their own backyards! Teachers receive structured lessons and interactive activities to address the Next Generation Science Standards for grades 3-5. Learning about their wildlife neighbors helps children to connect to their community and teaches children to consider how their everyday actions impact the natural world around them. A special thanks to Phillips 66 for their sponsorship of the Union County Educational programs utilizing the Union County Courthouse Falcon Cam.

Please contact Stephanie DAlessio, CWF Director of Education, for more information on this and other educational programming options.
